Fix arm-runner CI issue

[pguyot]

Add workaround for "Updating crates.io index" issue
Enlarge image to download build files
Bind mount repository as the goal doesn't seem to be to produce an image
Likewise, disable image optimization

Fixes pguyot/arm-runner-action/issues/77

I tested it and it works wonderfully. As you pointed out, I am not trying to create an image, but instead I wanted to use your ARM Runner to compile Raspirus as an executable (.deb file) for the Raspberry Pi. Currently, I am using the GitHub Runner to compile code for Windows, Ubuntu and macOS: https://github.com/Raspirus/Raspirus/blob/main/.github/workflows/tauri.yml
Is it possible to upload the .deb file as an artifact? On your project, I only saw examples on how to upload the entire .img file

[pguyot]

Yes you can upload artifacts.

If you use the bind_mount_repository: true option as in my PR, files created within the checkout directory will be accessible after the action is run.

So you can upload them using a standard upload artifact action.

Alternatively you can use the copy_artifact_path and copy_artifact_dest options.

The tests for these options can help:

Great, thank you!

@pguyot Sorry to bother you again, but I just noticed that the action takes about 4 hours to create my executable. I just wanted to know if there is something I could enhance, maybe some way of caching dependencies? If not it's ok, I can let it run overnight, it just shouldn't exceed the maximum of 6 hours, because GitHub would then forcefully terminate it.

[pguyot]

You can indeed use GitHub cache action.

Have you considered using cross-rust? At least to cross-compile some packages? It took 2 hours to install tauri-cli, while with cross-rust, it only takes 9 minutes.

See this build:
https://github.com/pguyot/Raspirus/actions/runs/5049517320/jobs/9059066053

With this workflow:
https://github.com/pguyot/Raspirus/blob/w20/use-rust-cross/.github/workflows/rasp-runner.yml

I didn't copy the rust compiled files, they should be copied to the repository's directory so they'll be available in the qemu environment, but I guess you can work from there if you want to explore this path. The trick was to select the features with the vendored openssl library.

Thank you for providing your example, the speed boost is impressive. I will do some more testing and see what else I can do outside the Runner. Especially caching dependencies might be a good idea. Thank you for your help again
